Title: Repeat spacing mechanism for typewriters
IPC: B41J25/12
Filed: 1970-07-31
Abstract: 1317805 Typewriters BROTHER KOGYO K K 31 July 1970 [4 Aug 1969] 37156/70 Heading B6F Letter spacing escapement mechanism in a typewriter includes a repeat spacing key 61 whereby the platen carriage is repeatedly stopped while the key is depressed. The key 61 is linked through a bell-crank 49 and spring 53 to a lever 46 carrying an inertial mass 47. When the key 61 is depressed, the spring 53 is tensioned urging the lever 46 counterclockwise against spring 48, and by engagement of lugs 46a, 18d urging a feed pawl 18c into engagement with an escapement ratchet wheel 16, whereby through stop 18g and lever arm 19c a keep pawl 19b is disengaged from the wheel 16. A spring drum 33 thereby acts to rotate the wheel 16 until a tooth thereon strikes feed pawl 18c. Such impact disengages the feed pawl 18c from the wheel 16, the keep pawl 19b being returned into engagement by a connecting spring 23. The spring 53 than acts through lever 46 to return the feed pawl 18c into engagement with the wheel 16 for a repeat spacing cycle. For normal operation, a space bar 45 or character key (not shown) acts through a lever 38 or 37 respectively to rock an actuator 24 having a roller 26 engaging an arm 18e of the feed pawl to urge the feed pawl into engagement with the wheel 16, impact disengagement of the feed pawl being prevented by the actuator 46 and by reduced tension in the spring 53. The inertial mass 47 is not moved during a single space operation.

Title: Improvements in and relating to methods for recharging continuous extrusion presses
IPC: B21C23/30
Filed: 1955-12-30
Abstract: 783,833. Extruding. SCHLOEMANN AKT.- GES. Dec. 30, 1955 [Feb. 23, 1955], No. 37397/65. Class 83 (4). In the extrusion of metal by forcing it through a die from opposite sides of the die axis, the metal is replaced from each side in alternate sequence whilst extrusion continues from the other side at reduced pressure. In a continuous extrusion process a pair of billets a, b, Fig. 2, are extruded simultaneously through a die by a pair of press stems 10 and recharging of a container is effected by reducing the pressure in both containers until a low extrusion speed is obtained, withdrawing one of the stems, Fig. 4 (not shown), from said container whilst the low speed extrusion is continued from the other container, inserting a new billet into the said container, and then continuing extrusion at full pressure from both containers. For commencing the extrusion process a half-size billet a is used initially in one container whereby the two billets will subsequently be expanded alternately. The friction of the extrusion residue prevents back flow of metal during re-charging. The press described is for sheathing cables with lead or aluminium and has a die 6, Fig. 1, secured in a die holder 5 by a plug 7, and a mandrel 8 supported in a mandrel holder 3 preferably formed integral with the die holder and screwed into a part 15 which is rigidly secured in the container 2 by a threaded plug 16. The die holder is prevented from rotating by a rib 1b. A number of webs 4 interconnect the die and mandrel holders and the extrusion metal flows between these webs to a common extrusion chamber 11. The mandrel holder may be separate from the die holder with the webs 4 omitted. The billet container is supported between a pair of container holders 2a, 2b with a through bore d. The extrusion orifice may alternatively be disposed on the centre line of the bore d. An example is given of the extrusion pressures used.

Title: Improvements in capacity loaded aerial conductors
IPC: H01B11/00
Filed: 1938-12-23
Abstract: 523,060. Aerials. CORK, E. C., and DEAN, J. N. Dec. 23, 1938, No. 37403. [Class 40 (v)] An aerial comprises a core of insulating material about which are applied layers of conducting material arranged in endto-end relation, adjacent ends of conductor being overlapped and insulated from one another so as to afford capacity loading. As shown in Fig. 1 a central core 10 ot string or rope or other insulating material of good tensile strength is provided and about this are braided sheaths 11 of copper wire, successive sheaths 11 being separated by gaps 12, Fig. 3, of length slightly less than that of the sheaths 11. Over the sheaths 11 is a layer 13 of thermo plastic low-loss insulating material over which are braided further conducting sheaths 14 so as to overlap the sheaths 11 and form the plates of condensers of which the insulating material 13 forms the dielectric. The sheaths 14 may be protected by a further insulating layer. Each time a complete sheath 11 has been braided the machine is stopped and a split disc 15, Fig. 3, of flexible or springy material is slipped over the core under the braiding wires, the disc having an inner aperture 16, Fig. 4, which grips the central core 10. The machine is then restarted and the next sheath is braided. The braiding is bound at points 18 on each side of the disc 15 to form bindings 19, Fig. 1, and the wires are then cut adjacent to the bindings and the disc 15 and the wires formed round it are removed. Alternatively the conductive sheaths 11, 14 may be formed by taping or wrapping sheets of conductor about the core. The layer of insulating material 13 may be replaced by a braided or taped layer of impregnated textile material. In a modification the conductive sheaths 11, 14 may all be applied directly on the core, the overlapping portions being separated by pads of insulating material. Specifications 490,414 and 493,758 are referred to.

Abstract: 956,490. Educational appliances. D. B. BAMBOROUGH. [Representative of E. S. BAMBOROUGH]. Oct. 18,1962 [Oct. 19, 1961], No. 37487/61. Heading G5G. An apparatus for teaching arithmetic comprises two sets of prismatic blocks Figs. 2 and 3, each block being of different length to represent a number, which is also marked off on the block by transverse grooves cut in the block. The set in Fig. 2, is called the smaller block set and incorporates the digits 1 to 5 all blocks being of the same colour. The set in Fig. 3, is called the larger set and includes the digits 6 to 10. To assist ready identification of the individual digits of the larger set, the side faces of the blocks have multi-coloured patterns marked on them e.g. the digit 6 is represented by two three-unit patterns in two colours, Fig. 3. In an alternative arrangement all the faces of one block may bear the same pattern, (Fig. 5, not shown) or different faces may have different patterns (Fig. 4, not shown). In the preferred embodiment the prism is of a square cross-section, but round, polygonal or triangular cross-section may be provided. The prisms may be made of wood, synthetic plastic or of compressed fibre. In other embodiments the prisms may be built up of magnetised unit blocks or the ends may be formed with inter-engageable pin and socket formations or they may be telescopic to permit subtraction operations. Also, instead of the prismatic blocks being of the same cross-section throughout their length, they could be of different sections to indicate different multi-unit patterns bonded into a number representation. A tray (Fig. 1, not shown) divided into a number of square compartments, with the length of sides suitable to accommodate the longest digit block, may be provided.

Title: A Dynamo-Electric Machine
Inventor: KOISUMI HISAO
IPC: H02K9/20
Filed: 1968-11-22
Abstract: 1,174,062. Cooling dynamo-electric machines. TOKYO SHIBAURA ELECTRIC CO. Ltd. 22 Nov., 1968, No. 37948/66. Heading H2A. In a dynamo-electric machine rotor whose conductors are directly cooled by the evaporation of liquid passing through them, the liquid is supplied by centrifugal action to the conductors from jets 20 projecting from a cylindrical header 19, the evaporated liquid being collected within a fixed insulating cylinder 5 surrounding the rotor. The conductors have channel-shaped ducts in which the liquid is retained by centrifugal force, but the vapour is free to leave and discharges from radial ports 17 from whence it is collected in the cylinder 5 and is returned via scroll 8 to the condenser 11. The liquid is fed to the machine through pipe 15 leading to the header 19. From nozzles 20 it passes into the conductors by entrances 32, Fig. 2, in the end-turns. The inwardly directed channels 22a, 22b, 22c of the conductors are interconnected by overflow channels 24 in the end-turns so that all the conductors may be filled in turn. The outermost conductors are interconnected by horizontal channels 25 connected to a liquid level adjusting ring 30 in which a band of liquid is centrifugally retained, and detected and corrected by a float (36, Fig. 5, not shown) to control the liquid feed to the rotor at valve 14. The quantity of liquid in each turn is maintained by a dam (50, Fig. 7, not shown) which prevents the liquid passing round the turn under centrifugal force. Spent vapour is exhausted from the top of each channel by passages 35, 17, Fig. 4, passing radially through the wedge 33. The interior of the sleeve 5 is pressurized and the pressure may be reduced to evaporate the rotor liquid rapidly in an emergency.

Abstract: 321,873. Hoe & Co., Ltd., R., (Hoe & Co., Inc., R.). Dec. 31, 1928. Delivery apparatus.-Mechanism for associating webs from a printing-machine comprises formers 11 over which the webs 50 pass, cutting- cylinders 22 - - 25 corresponding to the formers, and means intermediate the formers and the cylinders for separating some or all of the webs of one set and passing them separately to the cutting-mechanism of the other set. As shown in Fig. 1, three superimposed webs 50 are slit by discs 13 so that a set of six webs passes between each pair of rollers 14, 15 respectively, of the two formers 11. These may pass to their corresponding cutting, folding, and delivery mechanisms, or pairs of webs may be separated from one set 54 at rollers 16, 17, 18 and led over rollers 32, 33, 34 to the cutting-mechanism 24, 25 of the other set of webs. The separation of the webs avoids buckling of the webs liable to be caused by the abrupt change of direction with several superimposed webs. In a modified and more compact arrangement, two pairs of rollers are situated between the formers somewhat in the position of the rollers 32, so that double webs from the rollers 14 or 15 may be directed to the opposite cutters 24, 25, or 22, 23 respectively if desired. The cutters in this construction are arranged out of line with their respective formers.

Abstract: 1,244,156. Optical prism assemblies. HELIO MIRROR CO. Ltd. Aug.22, 1968 [Aug. 23, 1967], No.38746/67. Heading G2J. In an optical assembly, e.g. a periscope, comprising at least one prism but preferably first and second glass prisms 1, 2 sealed in a frame 3, 4, the prisms have spaced adjacent faces 5, 6 whereby a closed space 7 is defined in part by the faces and in part by the seal, the seal being formed by a relatively thin layer of hardenable plastic material 10, 11, which in its hardened state is resilient and strippable from the glass and a relatively thicker layer of harder material 8, 9 moulded in position between the prisms and frame. The thin layer 10, 11, which is preferably a polyvinyl chloride or polythioalcohol is applied to the prism surfaces by, for example, brushing on. If desired it may also be applied to the inner surfaces of the frame 3, 4 and as a plug 21, 22 between such coatings to act as a seal for the closed space 7. The thicker layer 8, 9 of harder material, e.g. a low melting point metal, is cast into the space formed between the thin coating 10, 11 and the frame member. To aid keying both the glass prisms and the frame member may be shaped as at 14-17. In a further embodiment metal inserts may be located between the thin layer and thicker layer with flanges which key into the thicker layer. These inserts may also help in reducing the effects of temperature fluctuations.
